Poll: Shaheen lead grows over Brown

A new poll on the potential matchup in the U.S. Senate race in New Hampshire, shows Democratic incumbent Jeanne Shaheen ahead of former Massachusetts Sen. Scott Brown, a Republican, by eight percentage points, up from just a three-point lead in the same poll a month ago.

The Public Policy Poll conducted on behalf of the League of Conservation Voters on Wednesday and Thursday showed Shaheen leading 47 percent to 39 percent over Brown.

Additionally, the poll showed Brown's personal favorability rating dropping seven percentage points in the last month. In January his next favorability rating was -6 percent and this month it is -13 percent. This change came at a time when the LCV has been heavily advertising against Brown in television ads.

Brown has continued to hint at entering the contest, but has not taken any active steps to do so this year, besides agreeing to speak at a Republican conference in Nashua and beginning to talk with Republican activists this week.
